Permanent-Magnet Synchronous Generators (PMSGs) exhibit high efficiency and power density, and have already been employed in gearless wind turbines. In the gearless wind turbines, due to the removal of the gearbox, the cogging torque is an important issue. Therefore, in this paper, at first, design of a Permanent-Magnet Synchronous Generator for a 2MW gearless horizontal-axis wind turbine, acco...

<span lang="EN-US">Single phase induction motor (SPIM) has zero torque, this many types and the main objective is to find starting torque of motor. This done by providing auxiliary coils that are mechanically separated or weakened after 75% engine speed. The real problem here these windings occupy a third iron core motor, when they weakened, capacity not fully used must withstand rated lo...

background and aims. the aim of this study was to assess the opening torque of grooved and non-grooved screws made of shape memory alloys (sma) for fixation of mandibular fractures. materials and methods. in this in vitro study the opening torques of ten sma screws with grooves and ten sma screws without grooves were compared in 20 holes (10 holes for grooved screws and 10 holes for non-grooved...

The purpose of our investigation was to compare, for the hamstring and quadriceps femoris muscles, peak torque values uncorrected for gravity with the peak torque values corrected for gravity and to determine the effect of making this correction on the hamstring to quadriceps femoris muscle peak torque ratio at slow and fast isokinetic speeds. We measured peak torques isokinetically at 60 degre...

The global burden of non-communicable diseases is rising, with continued projected increases in the prevalence metabolic syndrome (MetS) future. This epidemic, albeit a nature, poses broad socioeconomic and healthcare burdens worldwide. Population health improvement optimisation are important to addressing these burdens. Modelling systems be more health-centric—in addition being disease-centric...

Drive motors in certain applications often require heavy load starting or short-time overload operation, so the limiting output capacity of motor is worthy attention. In this paper, torque and input current low-speed high-torque external rotor surface-mounted permanent magnet synchronous motor(SMPMSM) under <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/19...

To achieve high efficiency and dynamics in electric drive applications, it is necessary to have accurate torque control. This typically accomplished through a current regulator that fed by references generated various open-loop control strategies, order obtain the desired torque. As an alternative, this work presents model predictive Starting from reference, algorithm generates optimal voltage ...

BACKGROUND Lower extremity torque steadiness has been shown to be an independent predictor of functional performance in older women. Hip muscle function is crucial for many types of activities of daily living, yet existing studies investigating torque steadiness for lower extremities are limited to assessing steadiness at the knee and ankle. OBJECTIVE The purpose of this study was to compare ...
